Grav is a **Fast**, **Simple**, and **Flexible**, file-based Web-platform. There is **Zero** installation required. Just extract the ZIP archive, and you are already up and running. It follows similar principals to other flat-file CMS platforms, but has a different design philosophy than most.
The underlying architecture of Grav has been designed to use well established and _best-in-class_ technologies, where applicable, to ensure that while Grav is simple to use and easy to extend. Some of these key technologies include:
* [Twig Templating](http://twig.sensiolabs.org/): for powerful control of the user interface
* [Markdown](http://en.wikipedia.org/wiki/Markdown): for easy content creation
* [YAML](http://yaml.org): for simple configuration
* [Doctrine Cache](http://docs.doctrine-project.org/en/2.0.x/reference/caching.html): layer for incredible performance
